SPECIFICATION forming part of Letters Patent No. 457,273, dated August4, 1891.

Application led December 3, 1890. Serial No. 373,493. (No model.)

.To @ZZ whom t may concern:

Be it known that I, DANIEL HALL, a Citizen of theUnited States, and aresident of New York, in the county of New York and State I vely, asthey are presented to or against the wind, and at the same time causingthem to maintain a position at right angles to the d1- rection of thewind during. their entire passage around their primary center ofrevolu-y tion-to wit, the center of the vertical rotary spindle-and alsoat the same time around their secondary center-to wit, that point in theradial arm of the vertical rotary spindle at which the sail-shaft ismounted-the whole .invention being fully illustrated and described inthe accompanying drawings.

Figure I represents a horizontal section of a wind-engine embodying myinvention. Flg. II represents a side view thereof, partly 1n section.Fig. III represents a cross-section on the line a: 0:, Fig. I. Fig. IVrepresents a like section on the line y y, Fig. I.

Similar letters of reference indicate similar arts.

p The letter A indicates the main shaft or spindle carrying the radialarms B in any desired number, preferably not less than three, and saidarms duplicated in rows perpendicularly one below the other to anydesired number of rows, preferably not less than two, at any point inthose arms, preferably near their outer extremities and equidistant fromthelr common center. Boxes B are mounted,con structed, and adapted toreceive and carry a perpendicular or vertical journaled shaft C, whichis to be mounted there, and which may be denominated a secondary or sailshaft. From the sail-shaft at points equidist/ant from and preferablynear to its j ournaled bearings are constructed arms D at right anglesto the perpendicular shaft. These arms are both dual and bifurcated andterminate at an equal length or distance from the shaft that carriesthem and each several pairs of ends connected vertically by a rigidrod-D. -Sails C', composed, preferably, of some material lof greatprehensile power in proportion to its weight, thickness, and superficialarea and with pivotal spines running longitudinally near or throughtheir centers, are mounted in sections by means of those pivots placedin bearings horizontally and vertically one above the other on the rodsD', connecting the ends of the bifurcated arms D of the sail-shaft C, orthe sail-shaft C, instead of being jonrnaled and mounted in boxes, asset forth, may be constructed hollow through its center from end to endlike apipe or sleeve and mounted at the same point on the radial arms Boccupied by the boxes B by means of a pivot-center running through thesleeve and firmly secured in aforesaid radial arms. Also, in likemanner, the primary vertical spindle,

instead of being rotary, may be made stationary, in which case it willact as a pivot, and the radial arms attached to a sleeve will revolvearound it, the one construction being the equivalent of the other,amounting simply to a change of journaled bearings. Each of the pivotalspines of the sails C'is provided with a crankarm C, which stands at anupward angle of forty-five degrees from the sailspine when the sail isvert-ical, and-the eX- tremities of each of these crank-arms is pivotedto a vertical connecting-rod f, having its lower end curved and providedwith an anti-f friction. roller at its lower end adapted'to ascend theincline D of the lower radial arm with the effect of shifting the sailsfrom a horizontal to a vertical position.

At the point on the lower one of the arms B cut by the circle and in theradius of the circle' described from the center of the sailshaft C bythe lower end of rod f is securely attached a permanent inclined planeto engage the anti-friction roller at the base of the rod f on itsapproaching a fixed point in its rotary passage, to wit-as it approachesthat point from which the wind is blowingfor the purpose and with theeffect of shifting the sails from a horizontal to a Vertical position.

Immediately in front and at mid-length of the bottom of the lowersection of the sail C is,

Vis supported by a bearing on the sail-shaft C.

From Vthe outer end of the rock-shaft E and vertically beneath it hangsthe crank-shaft F with the anti-friction roller F.

On the lower radial arm B and atthe point `on'i't cut by the circledescribed from the center of the sailshaft C at the distance measured bythe shorter end of the rock-shaft E and in its radius I place the lesserincline F2 to engage the anti-friction roller at a given point in itsrotary passage around the primary center in the Vertical spindle A-viz.,a point near that to which the wind is blowing-causingtherock-shaft E toperform onequarter of a revolution, and thereby throwing the spring-stopinto a horizontal position,with the effect of releasing the sail fromits vertical and allowing it to assume a horizontal position.

A permanent stop E2, as shown in Fig. II, is placed on the rigid rod Dto hold the sail in a horizontal line when against the wind or when theengine is stopped.

To stop the engine, it is simply necessary to keep the sails in ahorizontal position, and I elfect this by preventing the spring-stop Efrom engaging them when presented to the wind. This I accomplish bysuspending the rock-shaft G in bearings underneath the ra- -dial arms B,with thev incline G attached to its eccentric extremity beyond the endof the arm B and in the radial path of the anti-friction roller F as itapproaches the point from which the wind is blowing and the crank-arm F3on the other end near the vertical rotary spindle in such position thatwhen the crank` F3 is drawnfto a vertical position by means of thehand-rod H the rock-shaft G will make one-fourth of a revolution,causing its incline G on its eccentric end to rise up in the path of theroller F', causing it to turn the rockshaft E, so that its yielding stopwill be horizontal instead of vertical and allowing the sail to resume ahorizontal position.

To start the engine, it is simply necessary to release the hand-rods II,allowing the rockshaft G to revolve,when the weight of the ineline G onthe eccentric end of its rock-shaft will cause it to descend out of thepath of the anti-friction roller F. The engine being then moved forwardin the direction of the arrows, as the sail reaches the direction fromwhich the wind is blowing it will assume and maintain a verticalposition till it arrives at a point to which the wind is blowing by theautomatic action of the devices, as set forth, and for the purposes setforth.
